The Limited Scope ARRT Exam Skull/Sinus module is composed of 20 questions.  Statistically, this appears to be the most difficult of all modules.  Again, there may be a few questions on subject matter that we have not gone over.  Most of what you will see has been covered.  Some of the topics, along with the approximate number of questions on each topic you may see are listed below.  The radiographic positions and projections may include:

Skull- 8 questions

Sinuses - 8 questions

Facial Bones- 4 questions


It is recommended that you review the anatomy sheets, positioning sheets, and your textbook before taking the practice quiz.  Almost all information you will see on the ARRT exam will be found in one of those 3 areas.

Reading - This is just suggested reading as you've already had these assigned during the previous course.  The intent is just to review.

Additional Info

Understand what a contrecoup injury is. You can sustain a blow to the left side of your head and end up with injuries to the right side.  This is why it is common protocol to perform both left and right laterals on skull exams. 

Know all of the positioning lines used for skulls, sinuses, and facial bones.  This includes GML, OML, IOML, AML, LML, and MML positions (can be referenced on page 386)

Know all of the positioning landmarks associated with the above positioning lines.  This includes the glabella, orbit, infraorbit, acanthion, lips, and mentum.

For sinuses and facial bones, know why they are preferred to be done upright (air fluid levels). 

You will also want to make sure you have learned all the positioning terminology (prone, supine, anterior position, posterior position, etc)
